LAMP.

. SPECIFICATION forming part of Letters Patent No. 366.213, dated July 12, 1887.

Application filed May 29, 1586. Serial No. 203,635. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE P. GANSTER, of Reading, Berks county, in the State of Pennsylvania, have invented a certain new and use ful Improvement in Lamps, of which the following is a specification.

The following is a description of what I con- :ider the best means of carrying out the inven ion.

The accompanyingdrawings form a part of this specification.

Figure 1 isa central vertical section through the entire lamp. Fig. 2 is a diagram showing in plan the relation of the shaft and its tube to the two wick-tubes. The remaining figures show modifications. Fig. 3is a diagram showing in plan the shaft and its inelosing-tube with an Argand wick-tube. Fig. 4 shows in plan a single wick-tube lying alongside of the shaft and its loosely-inclosing tube, the wick-tube being curved in cross-section. Fig. 5 is a corresponding plan showing two wick-tubes in line with the shaft and its inclosing-tube between them.

Similar letters of reference indicate corresponding parts in all the figures.

A is the lamp-body, and A a tube, which may be of small diameter, extending centrally up from the bottom to a height above the level of the oil. This tube preferably extends up through the burner, and I will describe it as so extended. It is open at both ends. Its lower end is soldered to the bottom of the lampbody.

B is a burner provided with two fiat wicks fitted in two wick-tubes, b b. A sufficient hole is provided in the base of this burner to fit easily over the tube A, which, when all is in position for work, extends up through the burner, as shown in Fig. 1.

O is a casing covering the top of the lampbody, with a space between for the movement of air upward from the blowing means below.

C is the lower and main body of the casing, which supports the part 0 and also the body of the lamp.

D isa cylindrical'casing, of metal, mounted above the burner. Its top is crossed with an hole in the center.

intoa hood, D and supported on upright arms D connected to the casing G. A cross-bar, C in the base 0, supports a conical bearing, 0 a sufficient distance below the body A to allow the working of an efficient wheel to serve as a blower;

Eis the blower-wheel, formed with inclined wings to act screwwise. It is fixed on a shaft, 0, the lower end of which is pointed and turns without appreciable friction in the conical support 0 This shaft 0 extends up loosely through the tube A and far beyond it, and finds a frictionless bearing'in the spider D. Near its upper end is fixed a removable wheel, F, which is loosely inclosed within the casing D. When the lamp is filled and the wicks are adjusted and lighted, the hot air rising from the flame is gathered by the hood D and flows in a strong current up through the casing D, where it acts on the motor-wheel F, giving it a rapid rotatory motion. This by the shaft 6 communicates the same motion to the blowerwheel E. Thelatter, by the action of its screwblades, drives a sufficient current of fresh air up through the space between the body A and the casing O to supply the desired active current to induce complete combustion of the kerosene or other carbonaceous fluidl and give the clear flame desired.

The structure is easily taken apart when necessary. The burner may be unscrewed and lifted sufficiently to examine or replenish the oil, and replaced again without disturbing any other part. The supports D being fitted removably in sockets c on the casing O, the whole top work may be lifted off, and then the re movable wheel F being taken off the shaft 0 the burner may be unscrewed and removed. A reverse of this process restores all the parts again to place.

The action of myapparatus corresponds with that of the ordinary glass chimney in automatically starting, continuing, and stopping the current of air. It avoids the loss of light which a glass chimney involves.

Gis a telescopic top fitting tightly and easily on the exterior of the casing D. Its effect is to prolong the casing D. By raising and lower ing the tube G the height of the flue may be increased or diminished, and the force of the up ward flow of the hot gases, and consequently the speed of the shaft 6 and its connections, may be varied at will.

Modifications maybe made by any good mechaniein the form and details without departing from the principle or sacrificing the advantages of the invention. I can use a single wick-tube, instead of the two shown. In case asingle one is employed, it may be a fiat wick- 10 tube, lying a little one side of the tube A and its loosely-inclosed shaft, like one of the wicktubes b,- or it may be varied in form and position. I can use awick-tube of curved section with the shaft 6 and its tube A lying near but 1 5 out ofcontact with the hollow side. I propose to use an Argand burner, with the shaft e and its proper inclosing-tube extending up through the space in the center. The sockets which receive the supports D may be formed in a separate band and applied upon the lamp.

Parts of the invention may be used without the whole. I can dispense with the adjustable top G. Y

I claim as my invention 1. In combination with the lamp, the motorwheel F,arranged above the burner, the blower E,arranged below the burner, a shaft connecting said wheel and blower, and suitable supports, all adapted and arranged to serve as herein specified.

2. The combination, with a lamp and its surrounding casing, of the casing D, spider D, and hood D the motor-wheel F, the blowerwheel E, and the connecting-shaft 0 between saidwheels, all arranged to operate substantiall y as herein specified.

- 3. The lamp-body A, casing O O, blowing mechanism E, tube A, shaft 6, and motorwheel F, combined with casing D and its supports, all arranged to serve as herein specified. 4o

4. In combination with the lamp A, having vertical tube A, and the casing 0, arranged at a distance to form air-passages between it and the lamp-body, the shaft 6, the motor-wheel F, and blower E, arranged above and below 5 the lamp-body, respectively, the casing D, thespider D, hood D, and supports D and 0, all arranged for joint operation, as set forth.

In testimony whereof-Ihave hereunto set my hand, at New York city, New York, this 28th 0 day of May, 1886, in the presence of two subscribing witnesses.
